i am using datahub quickstart and have backed up datahub before nuke, but unfortunately after nuke i back up again. Is there any way i can restore the old backup before nuke??? Please help me

Hello Nam, all the metadata in DH should be in MySQL DB. we may not have the best answer since it really depends on how/where you back up the data.
h
Copy code
so data is deleted above Mysql db or not after i nuke?
b
it is not clear what "backup" you attempted. https://datahubproject.io/docs/quickstart#backing-up-your-datahub-quickstart-experimental if you did this backup, you should have a file created somewhere that is a SQL dump.
h
yes , i said that i am using datahub quickstart backup .
your answer is not clear ?
i ask if the old backup or old data is still in mysql , kafka ... or not ??
My understanding is that when I use backup , it generates a backup.sql file located in root/datahub/quickstart . So if I continue to backup, it will overwrite the old backup file, right? If so, is there a way to get the data back from the old backup?
b
is the sql file empty? that should answer your question. unless you specified a specific path name, it will write to the same file. once overwritten there is no more "old" file unless you have some linux backup

Are u the acryl's staff?
I appreciate your answer but i need a answer more detail
So if i using datahub nuke , did all data is deleted in mysql,kafka,es....??
b
you run quickstart, all the data in runtime in kept in docker volumes. you run datahub quickstart nuke, you erase all the volumes. So you have lost the data already. No, I am not Acryl staff.
